I'd say you're probably right, which is why he was shown at the 1943 expo as "The Synthetic Man" instead of "The Human Torch."

As to the OP, I strongly believe that AoU will derive its roots from the Captain America films rather than the Iron Man ones, with "The Synthetic Man" and Arnim Zola featuring prominently in MCU Ultron's origins.

As to the theory that Coulson might be that synthezoid: interesting possibility, but what's the basis for that hypothesis?

Are you sure it said "The Synthetic Man" though? Coulda sworn it said "The Human Torch" ?
